Keysight Completes Industry-First PSA Certified Level 4 Evaluation for Silicon Labs’ SiXG301 SoC

Keysight Technologies has completed the industry's first PSA Certified Level 4 security evaluation for Silicon Labs’ Series 3 Secure Vault™ on the SixG301 wireless SoC, marking a significant advancement in the security assurance of connected devices.

As IoT adoption accelerates across industries, the security threat landscape continues to evolve. Devices are increasingly targeted by sophisticated attackers with advanced tools and techniques. Certification frameworks like PSA Certified are critical in helping manufacturers prove that their devices can withstand these threats. Level 4, the most advanced assurance level in the framework, specifically tests the resilience of core security components such as Root of Trust (RoT), components, and secure elements (SE) embedded within connected platforms. These components are essential to protecting data, firmware, and device functionality throughout the product lifecycle.

As an authorized PSA Certified Test Lab, Keysight conducted the Level 4 evaluation through its advanced security lab, employing in-depth design reviews, vulnerability analysis, and sophisticated attack simulations such as Side-Channel Analysis and Fault Injection. These tests validated the product’s resilience against sophisticated threats.

While the initial plan was to achieve Level 3, Keysight’s deep expertise and flexible approach helped Silicon Labs achieve the top-tier Level 4 certification. This certification confirms the device’s robustness and Keysight’s critical role in helping customers bring secure, trusted technologies to market.
